National City — Parking

Last reviewed: July 2, 2026

Overview

This page explains how the National City Land Use Code regulates parking, loading, and bicycle parking for new development and for changes in use. The Land Use Code establishes minimum off‑street requirements, design/landscaping standards, special rules for mixed‑use and specific plan areas, and procedures for off‑site arrangements and site plan review. Key rules live in Chapter 18.45 (Off‑Street Parking and Loading) and the mixed‑use / objective design chapters such as 18.49; see the code citations when you need the exact language. § 18.45.010–020 and § 18.45.050 are the primary controls for counts and applicability .

Note: this page stays strictly within what the Land Use Code (Title 18) says. For building code (Title 24) or accessibility dimensions, see the California Building Standards Code linked below.

How to read this page

• Bolded zone names and numeric standards are taken directly from the Land Use Code.
• The first time the page mentions topics that connect to other GoCodebook pages they are linked inline: National City Zoning, National City Development Standards, National City Design Review, National City Overlay Districts, National City Landscaping and Screening, National City ADUs, and California Building Standards Code. Use those links when you want related procedural or standards guidance.

District-by-district breakdown (parking-focused)

Below are the districts and development contexts that the Land Use Code explicitly treats for parking. Each subsection summarizes purpose, typical uses that drive the parking counts, and the most decision‑relevant numeric or dimensional standards from the ordinance.

RS-1 (single‑family detached)

• Purpose & typical uses: RS-1 is the single‑family detached district; typical use is single detached homes. See definitions that list residential zones for context .
• Parking requirement: 2 covered spaces as a minimum for a single detached dwelling in RS-1, plus one additional uncovered space per bedroom greater than four or one additional uncovered space for dwellings greater than 2,500 SF, whichever is greater. This minimum is required prior to occupancy for new construction and in specified enlargements § 18.45.050 .
• Design/dimensional notes: driveways and stall sizes must meet the general parking design standards (stall sizes, aisle widths, vertical clearance) in § 18.45.100 .
• Where it applies: standard RS-1 lots citywide unless superseded by a specific plan (verify with the zoning map) .

Other RS and RM zones (RS-2, RS-3, RM-1, RM-2, RM-3 — general residential)

• Purpose & typical uses: lower- and medium-density residential and multi‑family housing. Definitions identify the list of residential zones .
• Parking requirement: for single detached houses in “all other RS and RM zones” the code requires one covered space and one uncovered space, plus additional uncovered spaces per bedroom as in the table; for multiple dwellings, parking is 1.3 spaces per 1‑bedroom unit and 1.5 spaces per 2‑bedroom (or larger) unit, plus guest parking (½ space per unit for up to 20 units, then ¼ per additional unit) § 18.45.050 .
• Tandem: Tandem parking is permitted only by the rules in § 18.45.055 (e.g., limited to multi‑family or mixed‑use units with three or more bedrooms; maximum 25% of a development may be tandem) .
• Design/dimensional notes: compact/tandem allowances, stall 9' x 18' (parallel 9' x 23'), aisle widths, and minimum vertical clearance 7 ft are in § 18.45.100 .

RS-4 (Westside Specific Plan)

• Purpose & typical uses: RS-4 is a Westside Specific Plan residential designation with modified parking ratios and allowances intended for that plan area.
• Parking requirement: the code lists RS-4 (Westside Specific Plan): Units greater than 1,200 SF — 2 spaces per unit; Units less than 1,200 SF — 1.7 spaces per unit in Table 18.45.050; additional shared parking/joint parking rules for the Westside are in § 18.45.060 .
• Tandem / mechanical lifts: two‑car tandem garages and mechanical lift allowances are provided in the Westside rules (see tandem/mechanical references in § 18.45.055 and related mechanical lift provisions) .

Mixed‑use zones (MCR‑1, MCR‑2, MXC‑1, MXC‑2, MXD‑1, MXD‑2)

• Purpose & typical uses: mixed residential and commercial districts; the code groups these as mixed‑use zones for parking and design rules .
• Parking requirement: parking counts for multi‑unit and mixed‑use projects must conform to § 18.45.050 and Table 18.45.050; however the mixed‑use chapter imposes location and frontage limits and special design rules — e.g., parking may not occupy more than 25% of site frontage and parking areas along side/private streets may not exceed 40% of frontage § 18.49.120 .
• Shared parking: The Westside specific rules and other mixed‑use provisions allow shared/joint parking arrangements and on‑site/off‑site joint use within specified distances (see § 18.45.060 for Westside details) .
• Cost and program rules: in mixed‑use zones parking costs must be separated from rent/purchase price and an employer parking cash‑out is required for places of employment in mixed‑use zones § 18.49.120 .
• Design/dimensions: mixed‑use developments must integrate and screen parking, provide pedestrian and bicycle access points at least 5 ft wide, and follow parking lot landscaping standards (e.g., 1 canopy tree per 7 spaces) § 18.49.120 and § 18.45.120 / § 18.45.100 .

Commercial and Industrial zones (loading‑centric)

• Purpose & typical uses: retail, wholesale, warehouse, and industrial uses where loading is a significant operational need.
• Loading requirement: for buildings in commercial/industrial zones the code requires, as a baseline, one 12' x 50' loading space with 14' height clearance per 20,000 SF (or fraction thereof) of building floor area or land use; for buildings 10,000–40,000 SF require one loading space; over 40,000 SF require one per 40,000 SF § 18.45.110 .
• Screening and placement: loading areas must be screened; loading berths over 25 ft located within 50 ft of a residential zone must be enclosed or screened by a masonry wall 6–8 ft high § 18.45.110 .
• Access: loading entries must allow vehicles to enter the street in a forward motion, and drive access points must be set back from intersections (at least 50 ft from intersection, 30 ft from residential lots) § 18.45.110 .

Key standards & decision table

Checklist (what an applicant must provide / satisfy)

• Confirm the zoning of the property (e.g., RS‑1, RM‑2, MXD‑1) and apply the correct row in Table 18.45.050 for the use § 18.45.050 .
• Provide calculations showing the required number of vehicle parking spaces and bicycle spaces (count before any vehicle‑parking reductions) § 18.45.120 .
• Show loading calculations and berth dimensions for commercial/industrial uses per § 18.45.110 if applicable .
• Submit a site plan illustrating stalls, aisle widths, driveway approach(s), pedestrian/bicycle access, landscaping islands, and screening consistent with § 18.45.100 and § 18.49.120; prepare to meet Site Plan Review requirements § 18.45.040 .
• If parking is off‑site, record a covenant/agreement acceptable to the city and show the certificate of occupancy linkage per § 18.45.030 .
• If proposing tandem, mechanical lifts, or stacked parking, document compliance with § 18.45.055 and mechanical lift rules (enclosure, screening, and approvals) .
• Show ADA/accessible stall counts and dimensions per California standards (Land Use Code defers to California Vehicle Code/Building Code for disabled stalls) § 18.45.090; coordinate with building code reviewer (Title 24) .

Risks & Ambiguities

Plain‑English summary

National City’s zoning code requires new and intensified uses to provide required off‑street vehicle parking, loading berths for commercial/industrial uses, and bicycle parking; the specific counts live in Table 18.45.050 and Table 18.45.120A, and parking design and screening rules (aisles, stall size, landscaping, and frontage limits for mixed‑use) are in the design sections; site plan review and recorded covenants (for off‑site parking) are mandatory as stated in the code § 18.45.050, § 18.45.100, § 18.45.030, § 18.45.040 .
